NICE(3) BSD Programmer's Manual NICE(3)
nice - set program scheduling priority
This interface is obsoleted by setpriority(2).
The nice() function obtains the scheduling priority of the process from
the system and sets it to the priority value specified in incr. The pri-
ority is a value in the range -20 to 20. The default priority is 0; low-
er priorities cause more favorable scheduling. Only the super-user may
Children inherit the priority of their parent processes via fork(2).
